the ute has started blowing smoke out the exhaust, my first thought was rings, but it only seemed to blow smoke after backing off and engine braking, i took off the dump pipes and found not much oil in the exhaust or back of the turbos. i degreased everything and left the car overnight, in the morning there was oil under the car and i traced it up to the back turbo which had a lot of oil inside the housing now

from this i decided the oil seal must be stuffed in the turbo, and i took it off and had it rebuilt. now i put the rebuilt turbo on and took off driving again. since then (only a week ago) it has been blowing a little bit of smoke after driving for say 15mins. but the last two days it's gotten a lot worse and pumping smoke almost constantly after driving for 10-15mins

initially i thought it was still blowing smoke cause there was probably left over oil in the exhaust from the dead seal

but last night i took the ute to my parents and left it there it was blowing smoke so bad

without pulling apart now i pressume it must be rings... but does this mean my turbo was ok?

im pretty confused

there is some blow by from the crank breather indicating the rings arnt entirely healthy but my turbo motors always had this even when they were going well


anyone able to shed some light on this one?

the other question is why would a setup make 15psi boost then after having a turbo rebuilt only make 8psi, but i wont even get started on that one here
